Recall Campaign Priority – If you have multiple active Recall campaigns with the same lapsing days (i.e., multiple 60 days lapse campaigns), you can set the priority with which they'll fire for a guest by dragging each campaign up or down within step 2 of any recall campaign. The higher up, the higher the priority; # 1 in the order will trigger first, then #2 in the order will trigger only if #1 has previously triggered, and so on.
NOTE that the priorities are not required to be sequential as campaigns that are not activated could removed from the list. For example, you could have priority 1,3,5,9 etc.
